Animal carcass incinerator

Abstract

An animal carcass incinerator designed to subject the entire external surface of the biomass material simultaneously to flame. The flame front burns inward toward the core of the material, greatly accelerating the burning process. Complete flame coverage of the biomass material is achieved by carefully shaping the internal surfaces of the incinerator. Burning gases are injected into a lower flame chamber. This lower flame chamber is bounded on its upper side by a grate, and on its remaining sides by the walls of the incinerator. Above the grate is a biomass chamber, where the animal carcasses or similar waste are deposited for incineration. The incinerator walls are lined with refractory insulating materials which incorporate a series of vertical flame channels. Likewise, the grate incorporates a series of vertical open channels. These channels are separated by raised ribs, which prevent the biomass materials from closing off the channels. The result is that even when the incinerator is jammed full of biomass materials, the burner flames still spread evenly around the entire external surface of the materials. A supplemental blower injects air to create a swirling pattern of flame within the biomass chamber.

1. An incinerator for burning animal carcasses, comprising:
 a. an insulated shell including an inner surface and an outer surface;  
 b. a grate, placed horizontally within said insulated shell, so as to divide a space enclosed within said insulated shell into a lower flame chamber and an upper biomass chamber;  
 c. means for introducing said animal carcasses into said upper biomass chamber;  
 d. a burner placed at a first end of said insulated shell and beneath said grate;  
 e. an exhaust stack placed proximate said first end of said insulated shell and positioned so as to vent said upper biomass chamber to a surrounding atmosphere; and  
 f. a plurality of channels cut into said inner surface of said insulated shell, wherein said channels are positioned to direct a flame produced by said burner evenly around said inner surface of said shell as said flame proceeds from said lower flame chamber, into said upper biomass chamber, around said animal carcasses, and out said exhaust stack.  
 
     
     
       2. A device as recited in  claim 1  further comprising a blower placed proximate a second end of said insulated shell, and oriented to direct a stream of air against said flame so as to roll said flame over said animal carcasses. 
     
     
       3. A device as recited in  claim 1 , wherein a second end of said insulated shell opens into a clean out door, with said door being positioned beneath said grate, and wherein said clean-out door is large enough to allow the removal of waste products from said lower flame chamber. 
     
     
       4. A device as recited in  claim 1 , wherein said grate includes a series of vertical grate channels which allow the passage of said flame from said lower flame chamber to said upper biomass chamber through said grate. 
     
     
       5. A device as recited in  claim 1 , wherein said means for introducing said animal carcasses into said upper biomass chamber comprises a main hatch opening through said insulated shell, with said main hatch being large enough to admit said animal carcasses. 
     
     
       6. An incinerator for burning animal carcasses, comprising:
   a. an insulated shell including an inner surface and an outer surface, having a first end and a second end;        b. a grate, placed horizontally within said insulated shell, so as to divide a space enclosed within said insulated shell into a lower flame chamber and an upper biomass chamber;        b. means for introducing said animal carcasses into said upper biomass chamber;        d. a burner placed at said first end of said insulated shell and beneath said grate;        e. an exhaust stack placed proximate said first end of said insulated shell and positioned so as to vent said upper biomass chamber to a surrounding atmosphere; and        f. a blower, positioned proximate said second end of said insulated shell, and oriented to direct a stream of air downward and toward said first end of said insulated shell.     
     
     
       7. An incinerator as recited in  claim 6 , wherein said second end of said insulated shell opens into a clean out door, with said clean out door being positioned beneath said grate, and wherein said clean out door is large enough to allow the removal of waster products from said lower flame chamber. 
     
     
       8. An incinerator as recited in  claim 6 , wherein said grate includes a series of vertical grate channels which allow the passage of said flame from said lower flame chamber to said upper biomass chamber through said grate. 
     
     
       9. An incinerator as recited in  claim 6 , wherein said means for introducing said animal carcasses into said upper biomass chamber comprises a main hatch opening through said insulated shell, with said main hatch being large enough to admit said animal carcasses. 
     
     
       10. An incinerator for burning animal carcasses, comprising:
   a. an insulated shell including an inner surface and an outer surface, having a first end and a second end;        b. a grate, placed horizontally within said insulated shell, so as to divide a space enclosed within said insulated shell into a lower flame chamber and an upper biomass chamber;        c. means for introducing said animal carcasses into said upper biomass chamber;        d. a burner placed at said first end of said insulated shell and beneath said grate, so that a flame produced by said burner travels through said lower flame chamber and through said grate into said upper biomass chamber;        e. an exhaust stack placed proximate said first end of said insulated shell and positioned so as to vent said upper biomass chamber to a surrounding atmosphere; and        f. a blower, positioned proximate said second end of said insulated shell, and oriented to direct a stream of air against said flame so as to roll said flame over said animal carcasses.     
     
     
       11. An incinerator as recited in  claim 10 , wherein said second end of said insulated shell opens into a clean out door, with said clean out door being positioned beneath said grate, and wherein said clean out door is large enough to allow the removal of waster products from said lower flame chamber. 
     
     
       12. An incinerator as recited in  claim 10 , wherein said grate includes a series of vertical grate channels which allow the passage of said flame from said lower flame chamber to said upper biomass chamber through said grate. 
     
     
       13. An incinerator as recited in  claim 10 , wherein said means for introducing said animal carcasses into said upper biomass chamber comprises a main hatch opening through said insulated shell, with said main hatch being large enough to admit said animal carcasses.
